描述了铁催化的富电子烯烃的区域选择性二碳官能化反应。特别是,芳基和烷基乙烯基醚被用作有效的连接键来偶联烷基或(氟)烷基卤化物和sp2杂化的格氏亲核剂。初步结果表明,在这些转化中,硫醚能够作为连接销并控制对映体选择性,这一领域在铁催化的三组分交叉偶联反应中很大程度上是未知的。本文描述了三组分铁-双膦催化的富电子烯烃的区域选择性二碳官能化反应。
An iron-catalyzed regioselective dicarbofunctionalization of electron-rich alkenes is described. In particular, aryl- and alkyl vinyl ethers are used as effective linchpins to couple alkyl or (fluoro)alkyl halides and sp2-hybrized Grignard nucleophiles. Preliminary results demonstrate ability to engage thioethers as lynchpins and control enantioselectivity in these transformations, an area which is largely unexplored for iron-catalyzed three-component cross-coupling reactions. A three component iron-bisphospine-catalyzed regioselective dicarbofunctionalization of electron-rich alkenes is described.
